This invention relates to improvement in catches for suit cases, boxes, chests, etc., the object beingI to provide a catch which is pro-` vided with a longitudinally movable operating finger piece and with a transversely movable locking dog,l togetherv with means for locking the catch in theclosedposition.

The invention consists in they construction as hereinafter described and particularly recited in the claims.

In the accompanying drawing Fig. 1 is a front view O'a clasp for suit cases, boxes, chests, etc.,- constructed in accordancewith my invention; Y

Fig. 2 is a side view of the same;

Fig. 3 is a sectional view on the line of Fig. 1, enlarged; Y y

Fig. 4 is a front View with the ace of the casing plate out away,sho`wing` the parts in the locked position;

Fig. 5 is a similar view with the parts in the unlocked position;

Fig. 6 is a sectional view of Fig. 4;- l

Fig. 7 is a. perspective view .ot the assembly plate, detached; 4

Fig. 8 is a perspective' view of the sliding plate, detached; and l Fig. 9 is a perspective view of the locking dog, detached. A i

In carryingout my invention, employ a front casing plate 10 having. itsk Ved'ges struck up to form a' top 11, sides 12a-nd bottom 13. The sides andb'ottoIrr areiormed with fingers 14 and with lugs 15 for the purpose as will hereinafter appear. f

The upper wall is formed with a slot 161V Mounted in the casing is'an assembly plfate 17 and provided at its upper end' are lugs 1.8 and' at its lower end are lugs 19. Its'sides are turned up to form flanges 20 and it is also formed, near its lower end, with a clearance opening 21 and at its lower edge, between the lugs 19, with .an extension 22 to locate the assembly plate in the casing 10.

A Mounted on the assembly plate is a locking dog 23 having a locking nose 24, and at one side formed with a beveled surface 25.V This dog rides upon lugs 26 struck fromthe vassembly plate 17 and the dog is adapted to be on the line 6-2-6' moved to its locking position by a spring 27.v

`Setting into the assembly plate is a sliding plate 28 formed with spacing lugs 29 and. at"l its top with an inclined cam edge 30 adapted to engage with the beveled edge 25'l vof the locking dog. 1 i

Arranged' between lugs 31 is a lock-turnl bier 32 formed in its lower edge' with a lOk-f ing shoulder 33 adapted to engage one of the lugs 31, and formed at itsfop'posite side with a locking tail 34 adapted to engage with "a finger 85 struck inward from the edgeV of the assembly. plate,-I the oppositev edge of f which has a linger 36 adapted to extend over thev sliding plate sol as to provide a- ,giguidev therefor. This tumbler is held in position is normally forced upward by a spring 38r bearing on a lug 39' on the sliding'- plate 28" and on the lugsV 19`Io the assembly plate.

A ringer' button 40 has prongs 4i which eX- te'nd' through a clearance opening 42 in the 'case` plate, through the clearance opening 2 in the assembly plate, and into engagement with 'slots 43' in' the sliding plate, over which they are turned. 4

The linger piece has a key slot 44 and the sliding plate is formed wit-lr a perforation 45 to' support the inn'erV end of a key. p'

The cov'er orto-p oit' the article on which the device is used is provided with a' hook 46 del pending from a cap: 47 which is provided with locking lugs 4.8,v and foilowsthe design f th`=e-lo`w`er end of thecatch. As" the' coveris closed, the hook 46 passe-'s through'V the slotl 16 hook 46 and allow the coverto be raised.,l

It thelocking mechanism is employed, a key will` 'be inserted through the key slot 44 and will engage withfth'ecam edge 49L of the tumbler, and avcontinued movement ofthe key will move the tumbler toV one sideps'o that kby a tumbar spring 37 mi the Sliding .plat-ei the shoulder 33 engages with the lug 31 and the end 34 engages with the inwardly pro- ]ectmg lug 35, so that downward movement thereof is arrested. In this position, the fingvelr piece cannot be moved.

ien, however, the key is turned in the opposite direction so as to engage with the cam edge 50 of Ithe tumbler, the tumbler will be lifted so that the shoulder 33 clears the lug 31 with which it is engaged,"andfthe tumbler is lmoved away from the lug 35 so as to clear the same, and the dog is `free to be moved by the finger piece.

I thus provide Vin a very simple way -a clasp for suit cases, boxes, chests, etc., which provides for a longitudinally movable finger piece and a horizontally movable locking dog which produces means Jfor holding the cover in its closed position and not liable to be disengaged byjarring, etc., and also means which provide for locking the cover initsl closed position bymeans operated only by the holder of a key tted for the particular lock, it being understood that the cam surfaces 49 and 50 may be variously changed to provide for differently bittedkeys.

I claim: n

l. A clasp of the character described, comprising a casing adapted to be attached to an article, an assembly plate mounted in the casing, a locking dog horizontally movable in said vassembly plate, said locking dog provided with a locking nose and with a beveled edge at one side, a sliding plate arranged on said `assembly plate and adapted to be moved vertically thereon, said sliding plate formed at its upper end with a cam edge adapted to engage with the beveled edge of the dog whereby the downward movement of the slid# ing platewillmove said dog'to one side, and means extending through the casing into engagementwith said sliding plate. Y 2. A `clasp of the character described, comprising a casing adapted to be attached to an article', an assembly plate mounted in the casing, a locking dog horizontally movable in said assembly plate, said locking dog provided With a locking nose and with abeveled edge at one side, a sliding plate arranged on lsaid assembly plate and adapted to be moved vertically thereon, said sliding plate formed ,at its upper end with a cam edge adapted to engage with the beveled edge of Vthe dog, whereby the downward movement of the sliding plate will move said dog to one side, means extending through the casing intoy engagement with said sliding plate, and a cap provided with a hook extending through the upper end ofthe casing and adapted to be engaged by said locking dog. p Y

3. A clasp of the character described, comprising a casing adapted to be attached to an article, an assembly plate mounted in the casing, a locking dog horizontally movable in said assembly plate, said locking dog protransversely movable key tumbler formed with a shoulder adapted to engage with a lug on the sliding plate and to be moved into engagement withl a stop lug carried by the assembly plate.

4. A clasp of the character described,'com

yprising a casing adapted to Vbe attached to an article, an assembly plate mounted in the casing, a locking dog horizontallymovable in said assembly plate, said locking dog provided with a locking nose and with a beveled edge at one side, a sliding plate arranged on` said assembly plate andadapted to be moved vertically thereon, said sliding plate formed at its upper end with a cam edge adapted to engage with the beveled edge oi. the dog, whereby the downward movement of the sliding plate will move said dog to one side, means extending ,through the casing into engagement withsaid sliding plate, a transversely movable key tumbler formed with a shoulder adapted to engage with a lug on the sliding plate and to be moved into engagement with a stop lug carried by the assembly plate, and a cap providedwith a hook extending through the upper end of the casing and adapted to be engaged by said lock- 7 ing dog.

ing dogrresting on said lugs and adapted to be moved transversely thereon, said dog formed with a locking noseand with a bev eled edge, va sliding plate setting over said assembly plate and provided lwith a cam edge engaging with the beveled edge of the dog, a'sprlng normally moving said sliding plateupward, and a lingerI piece outside the casing and extendinginto engagement with the sliding plate, whereby it is moved longitudinally. f

In testimony whereof, I have signed this specification. i
